Foredom Diamond Polishing Disc 4'' Dia. 80grit .5'' Ah

Description:

Diamond Polishing Disc 4" dia. 80Grit .5" AH is a robust, medium-coarse dental laboratory disc designed for precise contouring and controlled material reduction. With its 80-grit diamond coating, the disc provides a balanced combination of cutting aggressiveness and smooth operation, making it ideal for technicians shaping crowns, bridges, veneers, and implant prosthetics. This disc excels in contour refinement, helping technicians adjust occlusal anatomy, axial walls, and interproximal regions while maintaining the structural integrity of the restoration. The diamond-embedded abrasive surface performs efficiently on a wide range of dental materials including zirconia, lithium disilicate, feldspathic ceramic, composite resin blocks, and PMMA. Its cutting action is strong enough for shaping yet refined enough to transition into subsequent finer polishing stages. The 4-inch diameter allows for broad coverage and uniform finishing, reducing the time required for contouring larger restorations. Its .5-inch arbor hole provides compatibility with most laboratory lathes and polishing motors, ensuring secure and steady operation at various speeds. The disc�s reinforced construction reduces vibration and ensures technician comfort, especially during extended use. The 80-grit level is especially useful during the intermediate stages of fabrication where initial shaping has already been completed and the goal is to refine form without producing deep scratches that require extensive finishing. It also resists heat buildup, protecting ceramic structures from microfractures caused by thermal shock. With high durability, predictable results, and smooth handling, this disc supports efficient laboratory workflows and contributes to the creation of precisely contoured dental restorations.
